bcopy:
Be smarter about handling overlapped copies and only go backwards if it
is really necessary. Going backwards on a P6 is much slower than forwards
and it's a little slower on a P5. Also moved the count mask and 'std'
down a few lines - it's a couple percent faster this way on a P5.

replace the dozen other various hacks in the code that do all sorts
of crude things including spamming the envrionment strings with the new
argv string.
This version is mainly inspired by the sendmail version, with a couple of
ideas taken from the NetBSD implementation as well.
int shmget(key_t key, int size, int shmflg);
If the 'key' has already existed in the system and set 'shmflg'
as '(IPC_CREAT|IPC_EXC)', then shmget() must return the error 'EEXIST'.

libkern.a are now specified by listing their source files in
files.${MACHINE}. The list is machine-dependent to save space.
All the necessary object for each machine must be linked into the
kernel in case an lkm wants one.
list the processes belonging to a particular user without having to use
`-u' and grepping for the username. Basically you can now get a short
`ps -x' like list (with more space for the command) for other users.
-mprofiler-epilogue to support it and documented the option.
cc.1:
Listed all the machine-dependent options, even the temporary
debugging ones.
invoke.texi:
Fixed the sense of -mno-ieee-fp.
Sorted the machine-dependent options.
See the comments for addupc_intr() and the NetBSD implementation.
We use dummy versions of fuswintr() and susiwintr(), so addupc_intr()
always pushes the work to trap() (this is inefficient), and trap()
calls the special i386 function addupc() instead of addupc_task().
addupc() is more efficient than addupc_intr(), so some of the lost
efficiency is recovered. However, addupc() may be broken on plain
i386's since it doesn't check for write permission like copyout().
MOD_MISC() and DISPATCH() macros.
Renamed new_syscall module as new_syscall_mod. It seems to be standard
to have module names ending with _mod, and this may be forced when
MOD_SYSCALL() and MOD_VFS() are updated to match MOD_MISC().
Cleaned up lkm examples a little.
Two uninitialised variables were causing a phkmalloc warning (another notch
in phkmalloc's belt) and caused the full rcstemplate to not be constructed
for commits on freefall.
